Core Dump Panic String: assertion: cursor->flags & HAMMER_CURSOR_ITERATE_CHECK in hammer_btree_iterate

[Siju George]

Hi,

I don't think any body needs to waste time looking at my core dump.

I had as cron entry

#Check and restart mirroring
*/10 * * * * (cd /root/adm; /usr/bin/lockf -k -t 0 .lockfile ./hms) &

now hms was initially

dfly-bkpsrv# cat /root/adm/hms
hammer mirror-stream /Backup1/Data /Backup2/Data &
hammer mirror-stream /Backup1/VersionControl /Backup2/VersionControl

I had added a 3rd line some time and put an & at the end of the second line.
Now when I removed the 3rd line i forgot to remove the & at the end of
the second line and it looked like

dfly-bkpsrv# cat /root/adm/hms
hammer mirror-stream /Backup1/Data /Backup2/Data &
hammer mirror-stream /Backup1/VersionControl /Backup2/VersionControl &

So the locking did not work and it started spawning hammer
mirror-stream processes one after another every 10 mins.

I hope my slave pfses are not corrupted by these crashes :-(

Thanks

--Siju
