I've noticed on a large gmetad install (400 clusters) that some of the
data threads get stuck in the CLOSE_WAIT state, and cease polling the
gmonds. Other data threads are running normally. Over time, more and
more of the threads get stuck.
Looking at one of the threads, I found that it is stuck in hash_insert,
waiting for a reader to release a lock so that the writer can get the
exclusive lock.
Specifically, the hash_insert where it sticks is in process_xml.c:
rdatum = hash_insert( &hashkey, &hashval, xmldata->root);
Has anyone else seen anything like this?
