Crashing once every minute with the same stack trace; I'm going back to 4.0.20 for now.

[mistwang]

You can try the latest 4.1 build.

[andreas]

Same problem with 4.1 final.

[NiteWave]

please do a Force Reinstall for 4.1 if not yet.

[andreas]

The problem seems to occur with POST requests to Rails FastCGI apps.

[mistwang]

Please download and upgrade to the latest 4.1 std package. Just updated it.

[andreas]

Thanks, seems to work now!
