asp.net - A process serving application pool '{0}' suffered a fatal communication error with the Windows Process Activation Service. How to get crash dump? -

-

i have live standalone server running windows server 2008 sp2 (64bit) , iis7. running asp.net website built against .net 3.5 in own application pool. randomly @ different times of day, above error. may occur once per day, or more. when occurs, occur 2 or 3 times in relatively quick succession.

looking @ processes , logs leading crash there appears no real pattern or specific scenario causing it.

from searches, recommendations appear to crash dump , analyse it, struggling one.

i have debug diagnostics 1.2 installed, , have tried various crash rule setups, not create userdump. have 'crash rule iis/com+ related processes' default advanced configuration.

can suggest why isn't creating crash dump when issue occurs? there way crash dump?

edit: have installed debugging tools according useful link , running adplus using command:

adplus -crash -pn w3wp.exe -o c:\adpluscrashdump

hopefully crash dump when reoccurs . . .

edit 2: found recursive method call, caused stack overflow in rare circumstances. problem solved. found useful link however, see blog post.

i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines. ...
