Hi, there is a deadlock situation in openafs for linux-2.4 (at least in vanilla kernel 2.4.18 and CVS openafs version). linux-2.2, Solaris 8 and Irix 6.5 seems to be OK. Alias mc from RedHat 7.3 sometimes caused it when exiting mc. And this command causes it:
N=0; while true; do N=$(($N+1)); echo $N; (cp /etc/profile aaa &); cat aaa >/dev/null; done Here is a cmdebug output: --- ** Cache entry @ 0xc49a57d8 for 1.536877573.514.10221 locks: (writer_waiting, upgrade_locked(pid:1334 at:121), 1 read_locks(pid:1395), 2 waiters) 1003 bytes DV 4329 refcnt 2 callback c36c9100 expires 1023138509 2 opens 1 writers normal file states (0x21), stat'd --- pid 1334 is afsd, 1395 is cat afsd is holding shared lock on vcache->lock and is trying to obtain write lock in afs/afs_segments.c line 542 . cat called afs_UFSRead, there obtains read lock and called afs_GetDCache and then somewhere locks. I don't know where. Can it be linux-2.4 VM issue, or somebody has any ideas ?
