This file contains know bugs and incompatibilities
REPEATED LOG LINES
If multiple log lines with the exact same content are received,
the duplicates are NOT suppressed. This is done by sysklogd
in all cases. We plan to add this as an optional feature,
but as of now every line is logged.
ERRORS ON STARTUP
Error reporting on startup is not particular good. We handle all
errors correctly, but sometimes a message is only reported if
running in debug mode. If you experience some strange behaviour
I suggest to run the syslogd interactively with debugging enabled.
As of August, 2005, the situation has much improved. Keep in mind,
thought, that debug mode is your friend ;)
EQUALLY-NAMED TEMPLATES
If multiple templates with the SAME name are created, all but the
first definition is IGNORED. So you can NOT (yet) replace a
template definition.
MEMORY LEAK ON HUPING
Currently, the template memory is NOT freed when SIGHUP is received.
This causes a small memory leak on each HUP. Will be fixed soon and
should not cause real trouble unless you HUP syslogd quite frequently.
WALLMSG FORMAT (* selector)
This format is actually not 100% compatible with stock syslogd - the
date is missing. Will be fixed soon and can also be fixed just via
the proper template. Anyone up for this? ;)
CALLS to exit()
I have removed all calls to exit() I have introduced. However, there are
still some left from the original code. Most of them are OK, being done
on initial startup when a severe error happens. There are some, I think,
that might happen during runtime when a memory shortag is detected. We
should look into this issues. Finding some smarter code would allow
rsyslog to become even more fault-tolerant (but obviously, there is always
a cost, in this case most probably the loss of at least on message).
SIGPIPE HANDLING
Currently, SIGPIPE is ignored. This is necessary to handle broken TCP
connections. We should further look into this issue and see which other
ways exist to handle the situation.
MULTIPLE INSTANCES
If multiple instances are running on a single machine, the one with
the -r switch must start first. Also, UDP-based syslog forwarding
between the instances does not work. Use TCP instead.
