Incompatibility with suhosin extension / php memory limit issue?

Hi,

my server is reguarly running into internal server errors and the only time-related entries I find in the logs are the following:

May 31 21:30:36 suhosin[29535]: ALERT - script tried to increase memory_limit to 209715200 bytes which is above the allowed value (attacker ‘xx’, file ‘/piwik/core/SettingsServer.php’, line 177)
May 31 21:30:41 suhosin[29535]: ALERT - script tried to increase memory_limit to 209715200 bytes which is above the allowed value (attacker ‘xx’, file ‘/piwik/core/SettingsServer.php’, line 177)

May 31 21:30:57 suhosin[29520]: ALERT - script tried to increase memory_limit to 209715200 bytes which is above the allowed value (attacker ‘xx’, file ‘/piwik/core/SettingsServer.php’, line 177)

Shouldnt piwik recognize the allowed php memory limit and not try to raise it above that? Any help/hints would be appreciated!
thx,
