boost_server.php consumes 99% cpu

Post by dagonet »

Hi folks,
I have a problem with the boost plugin, especially with the boost_server:
when the boost_server runs and nobody accesses the cacti website everything's allright.
But if I access cacti after some 8h the boost_server consumes 99% cpu time and I see in the cacti logfile a lot of errors:
ERROR: SQL Assoc Failed "SELECT * FROM poller_output_boost_processes"

When this occures I have to stop and start the boost_server and everything is fine. Afterthat I can access the cacti website without any problems.

Regards
Dagonet

Are you running the server in multiprocess mode?

What version of the boost server. There are two out. Also, please answer Reinhard's question. What is PHP memory set to?

Thanks,

Hi,
@Reinhard: no
@Witness: boost plugin 1.1 and so the provided boost server,
php memory is set to 64 MBytes.

Looks like an Infinite loop. Let me see about the code. I'll check back to this post when I have more details as to "why" this may be happening.

Err, wait. Can you see if you have this table?

poller_output_boost_processes

So, this is what you need to do:

1) Start the boost server and redirect your STDOUT and STDERR to a file. Watch that file and post what you find.

Broken connection is as of my view not correct. I did a telnet to port 9050 and got a "Server Status Ok" reply.
And btw. I have the table poller_output_boost_processe.

Dagonet,

Please add "boost_server.php" to your array $no_http_header_files in "include/config.php" and see if the MM warning messages go away.

As far as the server broken connections are concerned, I will have to investigate and see if the updates process is forcibly disconnecting without a close request.

Ok, I added "boost_server.php" to your array $no_http_header_files in "include/config.php". The MM warnings disappeared.

Cool. Let me know if that fixes it. I have updated SVN with a more appropriate patch. Awaiting peer review from Cigamit.

Unfortunately the problem is not solved.
Right now the boost_server consumes 99% cpu and in the cactilog I have massive entries of this kind:

As well as connection broken errors in the logfile.

This is odd, the only way you would get a failure is if the table is damaged. Have you run a repair please.
