Hello.
Try, for example, the binary file Oscam, built by @juli13, from here: Oscam-EMU Mipsel & ARM (mipsoe20 or openpli40 or mips-emu-static-lib). Your set-top box contains a mips32el processor (so-called "mips" family), so use the binary for that processor.
(1) ps | grep -i "oscam" ...or... ps aux | grep -i "oscam" - as first, find the name and location of your current Oscam binary file
(2) /etc/init.d/softcam stop - stop current Oscam
(3) Now, download the new binary from the internet and replace the original binary file on your set-top box (before it, I recommend to backup original binary file, e.g. renaming to "/usr/bin/oscam-emu-backup").
(4) Copy the new binary to the original location (for example with the helping of FTP client in Total Commander).
(5) chmod a+x /usr/bin/file_name - set the execution rights attribute for sure again
(6) /etc/init.d/softcam start - start new Oscam
You can try setting the oscam process priority for the CPU, to "nice = -1": http://www.streamboard.tv/wiki…en/Config/oscam.conf#nice
You can also create a LOG file not only in TTY but in a file (logfile = /tmp/oscam.log "): http://www.streamboard.tv/wiki…Config/oscam.conf#logfile and then when crasnutí, look at the file to see if there will always be the same cause before Oscam freezes.
Also, you didn't show the configuration of your Oscam (of course, with the deletion of private data - login name, password, IP address, etc.), so it's hard to advise you.
