Litespeed stops responding for several minutes

[optize]

I have two boxes doing the same exact thing, it started 2 weeks ago or so.

Atleast once a day, Litespeed will stop responding for 5-10 minutes with nothing in the logs. I tried upgrading them to 4.2 last night and it did it again this morning.

There's really nothing in the logs, it just pretends like we received no traffic:

2012-11-04 07:25:15.150 [INFO] Remove pid: 981386, exitcode: 0

Litespeed didn't restart: Uptime 01:35:04

Anyone else running into something like this?
