Alfresco becomes inaccessible

konsultex — Thu, 05 Nov 2009 15:47:00 GMT

I'm using Alfresco 2.9b on Windows 2003 server sp2 with Sun JDK 1.6.0_14 64 bit on a well sized server (Xeon quad core, 24 gb ram). I installed this in Windows from the Alfresco Tomcat bundle quite a long time ago, around the time this version became available (in 2008 I believe). In the last months

In the meantime I tracked this down to a problem that seems to be related to the Alfresco ftp server. The application makes several ftp requests to Alfresco but after a certain amount (it does not seem to be constant) the ftp server seems to hang. Here is a log fragment (ftp in debug) showing this effect:

So it looks like something happens in Alfresco right after this line:
23:53:48,760 DEBUG [org.alfresco.ftp.protocol] FTP session request received from 172.16.0.6

and before this line:
23:53:48,760 INFO [org.alfresco.filesys.smb.server.repo.ContentDiskDriver] Added file state for pseudo files folder (getinfo) - \

I need to add that I tested Alfresco (same version) and the application on a different server and there it works fine.

Can somebody point me to where I can find a solution to this?

Thanks.
