After debugging together with some colleagues, I found a solution for this problem.

In the source code of report.c and snapshot.c (in the map ./web) there is a declaration in the main function: "char htmldelim[20];". In the same main function we can find: " sprintf(htmldelim, "xymonrep-%u-%u", (int)getpid(), (unsigned int)getcurrenttime(NULL));"

Because the size of "char htmldelim[20];" is not sufficient enough (requires around 25 or so) this process will crash. I changed this char value into 100 and after a "make && make install" command the issue seems to be resolved!

Hi all -

I'm running into a problem creating the availability report and the snapshot

on 4.3.0-beta2. Every time I run either command I get an "Internal Server

Error". The apache logs show "Premature end of script headers" and the

syslog shows that a buffer overflow was detected.

The system its on is a Ubuntu 9.04 64b server.

I have gone through the archives and based on what i did find i

double-checked permissions(all were good)..

Any ideas?

The other option I have is to try to recreate the report manually.. Any

ideas what datasets go into the report?

thanks!
