Dear all,

We are using Zimbra Open Source edition 7.1.1 in Ubuntu 10.04 LTS server. In the hardware with HP tower server with Quad core Intel Xeon 5410 2.6 GhzProcessor, 11 GB RAM, 500GB HDD. What we see is the POP3 or IMAP service get hanged randomly. After restarting all the services via zmcontrol then it works good.

we have installed only the core zimbra and we did not apply any patch to it. Is there any known issues related to our problem. If there any patch available for this problem. Please reply.
