Title
Syslog-ng PE Service Crashes on Microsoft Windows Server. I/O error occurred while reading. -
Description
The Syslog-ng service on Microsoft Windows Server crashes with one of the following errors:
syslog-ng[2012]: gmem.c:135: failed to allocate 268435456 bytes
syslog-ng[2012]: I/O error occurred while reading; fd='3036', error='Unknown error (10054)'
syslog-ng[2012]: Syslog connection closed; fd='3036'
-
Cause
The log_msg_size() is set too high and the Syslog-ng service does not have enough memory to continue. -
Resolution
Locate and edit the Syslog-ng PE configuration file on the Microsoft Windows Server running the Syslog-ng PE server and reduce the value of the "log_msg_size()".
64kb is recommended for most environments and should be supplied to the value in the form of bytes.
Example of a 64kb log_msg_size:
log_msg_size(65536)
-
Additional Information
The maximum value of the log_msg_size is 256mb which in byte form should look similar to the following: log_msg_size(268435456)
