Crash - Out of memory

Hello,

One of my Conquest server keeps crashing with the following lines in pacstrouble.log :

20141205 15:29:14 ***A fatal error occurred (out of memory) - closing server

It happened during transfer :

The server can operate perfectly during several days and then crash. It restarts but after several times it remains down, despite i set the "keep alive" option and the service set to "always restart" in Windows settings.

I updated to 1.4.17d but no change, i also tried to rebuild database, same result.
My server has 8 GB RAM installed and it should be enough i think. The pagefile is dynamically sized.
Any idea ?

Many thanks.

Thank you for your answer Marcel.
I use a Windows 2003 Server R2, 32bits indeed.
Guess i have to plan to migrate on a newer x64 system.

Just to be sure : Which size is very big according to your mind ?

Hi Marcel,

Indeed, users send some video since a month, so the cause is clearly identified now.
Do you think it will be fine if i upgrade my server with dgate64, and keep the same hardware, 8 GB of RAM ?
Or should i prevent users to send such sized video ?

Many thanks,

Hi Marcel,

I've just made a test on a Windows 2012 server (64bits):
The server can handle big files without crashing but the transfer fails because of the client (i think KPACS made a kind of timeout on large file transfer) on a study which contains a 1.5 GB file (!)
We can send such files to Conquest whitout any problem (even with dgate 32bits), but client can not retrieive without make Conquest to crash.
Since the 64 bits dgate does not crash i will consider to migrate my server to a 64 bits Windows server, and recommend the users not to send such files to the PACS.
I'll post here to keep you inform.

Again, thank you for your help Marcel.

I'm already using uj compression, but it's still the same :

20141210 11:35:26 ***[DecompressImage]: JPEG library decompression error

The good thing is that the server does not seem to crash now.

That said, migrate on a 64bits OS appears to be a good option, as Microsoft will also stop support for Windows 2003 server soon.

Hi Marcel,

I migrated on a windows 2012 server 64 Bits, updated Conquest to last version and it runs flawlessly since a month.
Some old clients like Kpacs are not able to retrieve large series but the server is not affected at all.

So, Marcel, i really want to thank you (again !) for the help you provide to all of us !
