Web app is crashing regularly
Added by Dave Soane over 5 years ago
Hi Guys,
My web site is crashing regularly, and I've isolated the problem to Wt.dll, offset 0x000c1d49. This is the latest version that I can use, which is MSVS2010, x86, 3.3.12. The exception code is 0xc0000005, Access Violation.
If I try and debug the executable, it says that Wt.dll was not built with debug info, which I expected from previous debug attempts, but this time it also said:
The procedure entry point
?idleTimeoutWApplication@Wt@MAEXXZ could not be located in the dynamic link library wt.dll
Is this not a further problem?
How can I fix, or work around these problems?
Dave.

I think you're getting that "procedure entry point" warning because it's maybe using the wrong wt.dll? idleTimeout is a pretty new method.
The release builds currently don't have any debugging symbols, so we can't really track down the source of your crash. You can of course try to test with the debug build if possible.

OK, sorry, I see the second problem was mine. I was using an older dll when debugging.
But for the first problem:
If I were to test with the debug build (I presume you mean deploying with the debug build), and were to get an offset after the next crash, how would that help? I am using the Wt binary releases, I have never compiled this locally.

I don't necessarily mean deploying with the debug build. If you can afford the performance drop you could of course do that. I'm just asking if you can reproduce it locally using the debug build. The Wt binary release includes debug libraries (wtd.dll, wthttpd.dll, etc.). Those do include debug info.

This crash hasn't happened locally.
I'll deploy with the debug build and see what happens. The site is still new and not very busy, so should be OK with the performance hit.
I'll come back after I've got more info.
Thanks for the help so far.
Dave.

OK, the crash (hopefully it's only one), has happened again.
I deployed the debug version entirely (the site is not too busy, so there were no performance issues). This is the info:
Faulting module name: wtd.dll, version: 3.3.12.0, time stamp: 0x5c19d410
Exception code: 0xc0000005
Fault offset: 0x00603875
Is that enough for you guys to go on, or must I download the source and come up with the actual source error line?
Dave.
