XenCenter will suddenly just stop working and requires a restart. There are around six pools being managed, with five of them running XS 7.1 and one on 7.0. The number of VMs supported on each pool varies from a few to in one case, around 350 VMs. Pool sizes vary from two up to five hosts. There appears to be no obvious correlation between the crash and ongoing activity, time of the day, etc. I will capture a crash notice the next time this takes place. What other information would you like me to gather to help diagnose this?
