Thanks all for your reply.
I store a structure in the serverConfig and most of the member get sets fro=
m the http config directives.. Two member of this structure are pointed to =
a hash Table which is not a apr.. This hash Table i create on post_config a=
nd added a cleanup function in the postConfig.=20
And for supporting the virtual host=2C i have server config Merger where i =
have another copy of the serverConfig and i set the members with the direct=
ives found in the http config and if not found will copy the base server Co=
nfig directives.=20
The hash table i don't copy instead i just copy the pointer of the base Ser=
ver config to the virtual config. =20
I guess the memory leak is because of this.=20
Do we have solution where we can use the base Server hast table in the virt=
ual host without any Memory Leak?
Thanks in advance=2C Jaysingh
