| So far, the now 6 'sync' processes have been stuck in "tstile" for 4
| days.
They are extermely unlikely to ever go away, that's a kernel locking bug.
What version is the system you're running (not the one you're building,
that's irrelevant to this) ?
You need a reboot to fix this.
| Other than being unable to build/link any kernels, the system is
| fine and its primary functions as file server (NFS, SaMBa, AppleTalk),
| backup DNS and NTP server are unaffected as are its clients (i.e., every
| other machine on my LAN). CVS updates to the various trees complete
| without problems.
Some little used vnode is likely locked. As long as nothing references that
particular one, everything is fine. Anything which accesses the file (in
the generic sense, ie: including directories etc) in question will hang.
| Once other clients are either finished with their tasks or at least reach
| a convenient stopping point, the machine will be rebooted so I can test
| a possible solution to kern/55115.
That will clear the lock... Whether it happens again or not all depends
on what was locked (not so easy to discover usually) and what caused it to
happen.
