Since updating clamd to 0.99.2-1.e15 on our RedHat 5 x86_64 system, it has failed to start successfully. The error we get is as follows:
LibClamAV Error: cli_pcre_compile: PCRE compilation failed at offset 52: unrecognized character after (?< LibClamAV Error: cli_pcre_build: failed to build pcre regex ERROR: Database initialization error: Malformed database [FAILED]
Freshclam works fine. I've even removed clamd, clamav-milter, and freshclam, then re-installed them (using "yum install clamd" and "yum install clamav-milter"), but even after running freshclam, I get the same error when trying to start clamd (using service clamd start).
I've been Googling this error and found a Mac OS X with a similar issue but the patch was not available
Please advise because I'm not sure how to correct this issue. It appears to be something with PCRE, but I'm not sure (we're running pcre.x86_64, version 6.6-9.el5).
