[Not Resolved] LSWS 4.1 - Spinlock

#21
we'd like to solve such issues as soon as possible, the problem is it's hard to reproduce.

have you tried MikeDVB's suggestion:
Yes, and it doesn't work, the server still "hangs". As far as I know my hosting sent bug reports to you, so you should have detailed knowledge how to reproduce it.

I'm seeing the same problem too, with the latest 4.1.10, didn't have this problem before with heavier server load and older version of lsws, really weird.
when the problem occured litespeed is using 100 percent cpu. also seeing possibly memory leak, litespeed is using alot more memory than usual over time.
