[rrd-users] Error from rrdtool: 'libpng error: stream error'

[Daniellek]

I wrote here in the begining of April about my problem.

Problem: While viewing rrdtool generated graphs, from time
to time (usually at least once a day), rrdtool starts 
printing endlessly 'libpng error: stream error'.

I use Cacti for generating graphs, and rrdtool is run from
php, so all such logs go to apache and are directed to 
error_log.

After the logfile is 2GB full of such messages it stops
writing (2GB file limit), load drops to normal level (0.1-0.4)
and everything from now is working perfectly.
I could live with 2GB file, but when it's full and i need to restart
apache it refuses to start (I need to delete the file, and then start
apache).

I've tried till now:
1) Recompiling apache+php
2) Recompiling libgd (but as far as I can see rrdtool uses it's 
   own version of GD library...)
3) Using different versions of rrdtool (now using 1.0.42).

Starting of error_log flood looks like this:
libpng error: Write Error
libpng error: stream error
libpng error: stream error
libpng error: stream error

Any suggestions?
