Changed the title to be noticed. :-) ---------- Forwarded message ---------- From: Xuekun Hu <xuekun.hu@xxxxxxxxx> Date: Mar 10, 2006 7:38 PM Subject: Re: [users@httpd] mod_mem_cache configuration help To: users@xxxxxxxxxxxxxxxx Thanks for replying. I tested mod_file_cache. However I also met some errors both with cachefile and mmapfile. When I want to cache more than 20 files, there are the below errors. Using cachefile: [Fri Mar 10 12:56:47 2006] [info] [client 10.0.1.4] (70014)End of file found: core_output_filter: writing data to the network [Fri Mar 10 12:56:47 2006] [info] [client 10.0.1.4] (70014)End of file found: core_output_filter: writing data to the network [Fri Mar 10 12:56:48 2006] [info] [client 10.0.1.3] (70014)End of file found: core_output_filter: writing data to the network ... Using mmapfile: [Fri Mar 10 15:32:03 2006] [info] [client 10.0.0.7] (14)Bad address: core_output_filter: writing data to the network [Fri Mar 10 15:32:03 2006] [info] [client 10.0.0.7] (14)Bad address: core_output_filter: writing data to the network [Fri Mar 10 15:32:03 2006] [info] [client 10.0.1.3] (14)Bad address: core_output_filter: writing data to the network ... While when caching below 10 files, all work fine. It seems mod_file_cache can't cache many files? My configuration is: 4 x Intel Xeon (EM64T) SLES9 SP2 (64bit) Is it a bug?
