Well, I am not a perl expert. But in your log_me function you detect that the logfile cannot be opened so you call log_me again.

This second invocation of log_me will also detect that the logfile cannot be opened so it will call log_me again.

This third invocation of log_me will also detect that the logfile cannot be opened so it will call log_me again.

And so on.

Shouldn't actually be infinite though. Each iteration consumes a bit more stack. Try letting it run for a few minutes. You gotta blow the stack sooner or later.
