Over the Memorial Day weekend dCache suddenly "crashed".  Everything looked "normal" but writes were timing out.  Tracked to "too many locks", and cleared by doing a vacuum on all postgres DBs.  A secondary issue then asserted, where the dCacheDomain was running out of memory (at 2g).  Increased to 3g and this problem resolved.  We have been running stably since that time.

Reminder that we will be down for a power outage from Noon on Friday, June 23 until sometime Monday June 26 when all services can be restarted.  We will do some software updates and dCache maintenance during this period.
