A fix for a syncprov modtarget deadlock is coming. I have only seen this happen once, during shutdown of one of the servers in test058, but I'm uncertain as to whether the shutdown condition was coincidental or not. It is probably the same deadlock as reported by Aaron Richton during 2.4.19 testing.
It looks as if syncprov was hanging waiting for a lock no-one held, possibly as a result of another thread removing the modtarget before or while it tried to acquire the modtarget mutex. If this is actually true, and if so why the lock and/or destroy calls didn't fail beats me... Anyhow, with this patch I have had test058 running without hanging for more than a week now.
