  • Applies to:
  • Plesk 10.x for Linux
  • Plesk 9.x for Linux/Unix
  • Plesk 8.6 for Linux/Unix
  • Plesk 8.4 for Linux/Unix
  • Plesk 8.3 for Linux/Unix
  • Plesk 8.2 for Linux/Unix


Symptoms from KB article Drweb rejects email with error "dwlib: fd: recv(4) failed - Connection reset by peer"  are reproduced after a Parallels Plesk Panel upgrade.


MaxChildren option in drweb32.ini is always rewritten with value 4 when there is an install/upgrade of package psa-drweb-configurator.


Before an upgrade, make a copy of /etc/drweb/drweb32.ini file:
# cp /etc/drweb/drweb32.ini /etc/drweb/drweb32.ini.copy
After an upgrade, replace MaxChildren value of /etc/drweb/drweb32.ini by value from a copy made before upgrade.
