PHP is dead slow, pulling my hair out...

Anon

The strange thing that it slows down
dramatically at the same time, on 58th min of every hour and continues to be slow for
the duration of 5-20 mins and then goes
back to normal uptill next 58th minute.

if anyone has any idea what
the problem might be please help.
TIA
(it also affects ftp somehow but normal html
pages seems to be more or less OK)

Try to start the "top" utility a see what other processes are started at that time.It's a good start to find the botlenek.
Another thing is too look in the apache and message logs to see fore some strange things like timeouts mesages ,coredumps and thinks like that.

It's a hard task (sometime ) to find tinks like this.
Hope to help.

Most likely you have a cron job running at the 58th minute of each hour.

try the cmd "cron -l" from the prompt and see what is set to run.
