This regex: is there something bad there?..

[Doctrin]

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?

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.
