We have a customer that's seeing a very slow memory leak under certain circumstances that we haven't yet been able to pinpoint. I can reproduce it, but it requires a very particular method of downloading files that I don't quite understand yet. (not entirely sure how this would impact mod_jk either). Our customer is still on an older mod_jk 1.2.37 but I'm able to see the behavior on 1.2.40.
They had Microsoft analyze a memory dump and Microsoft came to the analysis that mod_jk was leaking 8k at a time and this is the stack of each allocation: Function Destination libapr_1!apr_palloc+212 msvcrt!malloc libaprutil_1!apr_brigade_create+11 libapr_1!apr_palloc libhttpd!ap_rflush+19 libaprutil_1!apr_brigade_create mod_jk+3183a libhttpd!ap_rflush mod_jk+9729 mod_jk+f3bd kernel32!TlsSetValueStub ntdll!_except_handler4 msvcrt!_except_handler4 ntdll!_except_handler4 ntdll!FinalExceptionHandler msvcrt!_threadstartex I'm far far from a Windows developer :( so I'm slowly getting a system configured to do the debugdiag analysis that Microsoft did with the pdb files to get the actual symbols. This will take me some time so I thought I'd mail here to see of anyone has seen anything similar or if there's any thoughts on what would be slowly leaking the 8k through mod_jk. If not, I'll try to get the real stack shortly once I get debugdiag figured out. Thanks, Andy
