Version 4.5.24 of mod_wsgi can be obtained from:
Using mod_wsgi in daemon mode on Solaris would cause a process hang or max out CPU usage. Caused by change of variable type to unsigned to get rid of compiler warnings, without fixing how condition check using variable was done.
Problem could also affect non Solaris systems if total number of HTTP headers and other variables passed in WSGI environ was greater than 1024. Affected Solaris all the time due to it having a limit of only 16 in operating system for same code, meaning hit problem immediately.
