'SEVERE: Socket accept failed' error

[mautidavis]

Dear all,

Iam getting this error on my catalaina.out log file although my Alfresco is running OK with some challenges when a user tries to access their profile - this occurs intermittently. What might be the problem?

It looks to me like an issue with your JVM settings.  Have a look at http://wiki.alfresco.com/wiki/Repository_Hardware and see if tuning will fix your problem.
