Track down those posts for info, there's a pending-confirmation fix in CVS as well as a workaround (move your status.dat file back to the same filesystem).

I've been running this setup for some time and just recently started seeing "Internal Server Error" on page refreshes from Firefox, with Apache reporting "Premature end of script headers". The only changes recently are that I increased the host and service checks significantly (up to 250 and 5200 respectively) and I moved status.dat from a UFS file system to /tmp (tmpfs) per the performance page tip #2 on using RAM-based filesystem for it. I searched the mailing list archives and turned on debug level logging in Apache but it doesn't report any more. If I run status.cgi from command line, it dumps core for a seg fault as shown below. I tried the status.cgi from 2.3 with the same results. If I move status.dat back to disk, the CGI errors stop, but I still get a seg fault running from command line. There are no core files created when the error occurs from Apache. Any idea why this may be occuring? Here's some command line output. bash-3.00$ ./status.cgi Cache-Control: no-store Pragma: no-cache Refresh: 90 Last-Modified: Tue, 30 May 2006 14:00:55 GMT Expires: Thu, 01 Jan 1970 00:00:00 GMT Content-type: text/html <html> <head> <title> Current Network Status [ snipped ] V CLASS='hostTotals'>Host Status Totals</DIV> <TABLE BORDER=0 CELLSPACING=0 CELLPADDING=0> <TR><TD> <TABLE BORDER=1 CLASS='hostTotals'> <TR> Segmentation Fault (core dumped) bash-3.00$ file core core: ELF 32-bit MSB core file SPARC Version 1, from 'status.cgi' Here's the tail'd output from truss. write(1, " < T R >\n", 5) = 5 Incurred fault #6, FLTBOUNDS %pc = 0xFF230BF0 siginfo: SIGSEGV SEGV_MAPERR addr=0x00000000 Received signal #11, SIGSEGV [default] siginfo: SIGSEGV SEGV_MAPERR addr=0x00000000 -- - Kyle --------------------------------------------- kylet@panix.com <A HREF="http://www.panix.com/~kylet">http://www.panix.com/~kylet</A> --------------------------------------------- -- - Kyle --------------------------------------------- kylet@panix.com <A HREF="http://www.panix.com/~kylet">http://www.panix.com/~kylet</A> --------------------------------------------- ------------------------------------------------------- All the advantages of Linux Managed Hosting--Without the Cost and Risk!
