This regex: is there something bad there?..

Doctrin has asked for the wisdom of the Perl Monks concerning the following question:

Hello dear Monks! I suspect that following regex puts the server down (sic, it is executed much times). So, is there something bad in this regex? if($Inapp=~/refill_(\d+)\.$/){ I don't know how and why, but if I put if(0) here, all is OK :( I've made the body of condition completely EMPTY for tests to be sure that regex is the case. So, when I try to browse a page, generated by a script containing this regex - it hangs forever. And if I get rid of this regex - all ok. Is there any reasonable explanation of that (including my stupidity, maybe)? UPD: Thanx, problem resolved; the regex was not the case...

There's nothing wrong with the regex. It will change `$1` however. Is your code using `$1` after the if and going into an infinite loop because the value isn't what you expect?	[reply] [d/l] [select]

This regex looks fine to me. Is there any that is using this regex below that piece of code, look in to that as well i guess it might be the problem. ==dEEPAk==	[reply]
