FOP2 server issues

[krzykat1]

Every couple of days i do get a complaint from my boss that he can't access the FOP2 panel. When i check the error on the bottom of the webpage i see that FOP2 reports that it can't connect over port 4445! The problem gets resolved by issuing the following command, (rm /usr/local/fop2/fop2settings.db) followed by restarting the FOP2 service. Is there a permanent resolution to this?!!

MORE INFO:
1- This is a licensed version of FOP2.
2-When i run the command (/usr/local/fop2/fop2_server -X 15 -i eth0) i get the following error
(server/fop2_server: symbol lookup error: /tmp/par-726f6f74/cache-42500eee0cc6d9b9f21916d9c1dace54f3fc476d/libssl.so.6: undefined symbol: CRYPTO_memcmp)
3- my /etc/sysconfig/fop2 has a line that states --> OPTIONS="-d --rp=http"

Any help is much appreciated.

Hi,
Usually that libcrypto error is fixed by installing the openssl compat library as described in this entry in the FAQ

If your OS does not have that library, or if the error still happens after installing it, then you must always use the --rp=http when running fop2_server, so, on step 2, you should run the command adding --rp=http at the end of the parameters list. Whenever you invoke ./fop2_server via the command line, you should add it, otherwise the fop2settings.db might get corrupted

Finally, the error you experience might not be related at all with the fop2settings.db corruption you see. The way to troubleshot would be to add debug parameters to the /etc/sysconfig/fop2 file, something like

OPTIONS="-d --rp=http -X 511 -l /var/log"

and let it run with debug, once you notice the error, then look at the last lines on the log when there are connections attempts to FOP2, or in general look for any kind of errors, mostly you might want to check for the string "EV" on the logs.

Well, it took a few days to fail this time, here is the offending part of debug:

What do you think?

Hi,
Never seen that happen, do you recognize the ip that connected to FOP2 before the problem? 51.91.212.81?
Try uninstalling openssl098e (yum remove openssl098e) and always use --rp=htttp when running fop2_server, to see if it makes a difference.
