Out of Memory exception

Hi,

I've just been reading the previous thread reqarding the out of memory exception (http://www.DynamicPDF.com/Forums/DisplayThread.csp?ForumId=17&ThreadId=2560), I'm also getting the error intermittently and not necessarily with large files. Usually I just rerun the request and it works, but I've just had an instance where by the error was raised repeatedly, eventually I restarted the DynamicPDF Converter service and then it worked okay. I also noticed that there were two instances of "ceTe.DynamicPDF.Converter.Service.exe" running in the processes list <-- is this right?

Regards Allan

Hello,

The Converter process should only show up once in the list of processes. Can you please download and try the latest build from the website that was released early this week? It has few bug fixes and also has logging capabilities that will enable us to troubleshoot this more effectively.

Thanks,
ceTe Software Support Team

Hi,

Thanks for your reply. I've uninstalled and reinstalled -

Merger - DynamicPDF512forNETBuild15141.msi
Converter - DynamicPDFConverterv100forNETBuild16128x86.msi

Are these the latest versions?

I've updated the references to the dlls in my project (ceTe.DynamicPDF.20.dll, ceTe.DynamicPDF.Converter.20.dll)

Deployed and run a test through the converter and I've still got two instances "ceTe.DynamicPDF.converter.service.exe" in the processes tab of task manager.

Do you have any advice for implementing the logging you mentioned?

Hello,

You are seeing two instances of the "ceTe.DynamicPDF.Converter.Service.exe" in the processes tab of Task Manager because one is the manager process and other is the actual conversion process. One is the actual service and other is invoked by the service on receiving the first conversion request. Conversion process gets recycled every 1000 conversions, which can be modified by changing the value of the conversionsPerProcess attribute in the ceTe.DynamicPDF.Converter.Service.exe.config file.

To enable logging, please follow the steps below:

1. After installation, Open the Service Config file under the Service folder (ceTe.DynamicPDF.Converter.Service.exe.config)
2. Edit the enableLogging property and set to "true"
3. Re-start the DynamicPDF Converter service from Administrative Tools --> Services
4. The log file will be created under %windir%\temp. DynamicPDFConverter.log will be created if no errors occur and DynamicPDFConverterONLOGERROR.log will be created if there are errors.

Send us the log file that gets created and that will help us troubleshoot this more effectively.

Thanks,

Hello Allan,

Please try converting only the tiff image file to PDF using our DynamicPDF Converter product and see if it works for you?

Can you please send over the Tiff image which you are using for conversion process to our Support Teamso that we can do some testing on our end by setting up the similar environment? This will help us to find the cause for the error.

Thanks,
ceTe Software Support Team

Hi,

I've managed to convert just the tiff ok, plus when I run this directly on the server it all converts okay when I run it from the network, there is a delay in the file delivery. I've also add a convert to jpg for tiff's which has reduced the file sizes massively which has also helped.

I've been struggling to put together a routine to check the file delivery as the file.exists and file.length >0 return true even though the file isn't completely accessible.

Allan

Hello Allan,

Can you please explain what exactly you mean by delay in file delivery? Is it delay in generating the output PDF after the conversion or delay in accessing the source file for conversion?

So TIFF conversion is working fine for you? Is there anything on our end that we need to troubleshoot further?

Thanks,
ceTe Software Support Team

Hi,

We have a 3 server failover system with a master server which holds all the web files, any editing is done on the master and replicated to the 3 failover servers using a realtime replication tool called doubletake. We have a service which polls the three servers and if it doesn't get a response from any one of them it changes the dns records to point to one of the servers that is up.

So sometimes there can be a short lag in the replication especially if the network traffic is high.

My tests seem to indicate that if I call the conversion routine before all the files have replicated completely I get this out of memory error. If I put in a long enough pause between copying the files and calling the conversion process if works okay.

The out of memory error is somewhat misleading.

As I mentioned in my previous post I'm having a bit of trouble figuring out a reliable method of establishing if a file is truly available for processing.

Regards Allan

Hello Allan,

Can you please check if the file exists in the server where you are converting the file before calling the conversion method? This may solve the problem. If the file exists then you can convert it and if it is not exists then you may have to keep the files so that you can convert them.

Thanks,
ceTe Software Support Team.
