Bug #: 52282
Summary: Apache2 exit signal Segmentation fault (11)
apr_bucket_free
Product: Apache httpd-2
Version: 2.2.20
Platform: PC
OS/Version: Linux
Status: NEW
Severity: blocker
Priority: P2
Component: All
AssignedTo: bugs@httpd.apache.org
ReportedBy: nickdrago...@gmail.com
Classification: Unclassified
I am running Apache2 with mod_fcgid and am trying to upload a 700MB file. By
the end of the upload proccess Apache dies with:
exit signal Segmentation fault (11)
however I am able to upload smaller files (around 200MB). PHP settings allow me
to upload up to 2GB files as well as the mod_fcgid directive MaxRequestLen.
I have tried to backtrack the error and this is what I have on a gdb command:
Program terminated with signal 11, Segmentation fault.
