Hi community,

I recently experienced periodic alfresco server crashes and i can't figure out why !

I'm running alfresco community 5.1 on AWS machine (Ubuntu 16.04, 14Go RAM, Xeon E5 2.5Ghz) ..

In the log file (catalina.out) i get 'usual' errors like :

          Failed to execute script ... thumbnail.get.js

         Input stream invalid - skipped for source: classpath:alfresco/web-extension/share-config-custom.xml'

But nothing unsual after the server crash.

So i monitored alfresco service with munin/xymon and i noticed a sudden high use of memory and file system read/write just before the crash (see image attached).

The alf_data is mounted as an efs partition (i changed the dir.root directory)

Does anyone have a clue on what's happening ?

I'll appreciate any help.

Thank you.

Azzedine.

Hello.

What were the users doing when the crash happened?

Were you performing any batch processing?
