Hello, Wondered if anyone have any idea about below. If started with flag -X everything starts up ok but without -X then it crashes with these messages in the log.(atleast most of the time if one is persistent then it may well start up properly sometimes without the -X flag) As soon as it starts ok then there seems to be no problem whatsoever. It runs perfectly with the same config and perl hooks at a lab machine where there are no traffic. Searching through the web doesn't give much info? Any ideas would be appreciated. Thank you.
