Hello all,
I suppose it's all been going smoothly for too long here at Lancs. Our
dcache SE has started going flakey on us, we find that attempts to
transfer files, using lcg-cp or even plain srmcp give "end of file"
error messages and deliver empty files. A restart of the dcache
services fixed this the first time it happened on Wednesday. Then we
keeled over again later that night. So I made sure everything was up
to date, and restarted it all again. We made sure transfers worked,
and left it. Then it broke again this morning. I'm not sure what's
wrong.
Our symptoms are similar to the ones detailed on this thread on the dcache site:
http://www.dcache.org/archive/user-forum/0307.shtml
However, we have no OutofMemory type errors in our logs as was
suggested to look for in that thread.
What we do see in our dCacheDomain.log is many messages of the flavour:
07/07 09:27:34 Cell(PoolManager@dCacheDomain) : PnfsHandler :
CacheException (4) : Pnfs error : Pnfs lookup failed
Any ideas? I'm stuck.
Thanks in advance,
Matt
