[atvcaptain]

to check this , we dont have and paytv smartcard from this provider, is this possible only with fta channels on hotbild or astra ?

[ghost]

Yes! It's very easy to reproduce. Smartcard or softcams aren't necessary. Perform a clean install if you considered. Enable MHW2 EPG. Scan the transponder: 10847.00 V DVB-S 22000 5/6 (19.2E Astra 1M). Now you have got the SID 30150 PORTADA where the provider sends the EPG for all services. Watch this service for about 5-6min while you see the log of enigma or mhw_Log.epg. The segfault will occur after this time. I've pasted some logs with this bug above. Thanks for your attention.

[atvcaptain]

then you enable the function and dont leave the menu have you the segfault too after 5-6 min

[ghost]

No, I perform a restart GUI after enable MHW2. Then, when I try to watch the SID 30150 and enigma2 starts to received the EPG (startEPG [EPGC] start caching events), enigma2 crash just after "finishEPG [EPGC] next update in 60 min". For other services with MHW2-EPG for its transponder only, enigma doesn't crash and work properly.

[ghost]

Atvcaptain, I've tried your option. Enable function over service PORTADA, but doesn't update EPG cache until 60min. If I enable function over other service and change to PORTADA, download EPG begins but crash enigma2 with this log:

[pizzelnet]

I don't know if this could help. This problem only happens when you set 4 or more days as the maximum number of days to download the EPG. If set in 3, the MHW2 EPG downloads very fast and Enigma2 GUI does not crash and restart. Other images such as OpenSPA and OpenLD got rid of this problem by deleting this function:

    bool save_epg = eConfigManager::getConfigBoolValue("config.epg.saveepg", true);
    if (save_epg)

So I guess the problem should be related with it.

[ghost]

I'll test this: https://github.com/djMesias/enigma2/commit/1268d95e7869bb20fe818cbedf2e98aaf4102c05 because mhw2 for <4 days works (thanks @pizzelnet), and that function doesn't save cache. Maybe this is the solution.

@pizzelnet, save_epg works properly, and this function is called on exit enigma2 or by timer. Can be remained.

[ghost]

@atvcaptain I've tested https://github.com/djMesias/enigma2/commit/1268d95e7869bb20fe818cbedf2e98aaf4102c05 and it solves the problem for mhw2 epg if is set 4 or more days. In my humble opinion it can be merged.

PD. This provider is not sending correctly the epg through SID 30150 just now, but without this patch segfault is here too.

PD2. @pizzelnet your solution works too, but it saves the epg always, without the user's approval: https://github.com/djMesias/enigma2/commit/986521d985720232b813a1c1975e119dcfb1c272

[atvcaptain]

@djMesias i see test2,3,4 etc all or only last ?

[ghost]

@atvcaptain I've created a new pull request with the correct patch (my test2 branch). Thanks. https://github.com/openatv/enigma2/pull/433

[atvcaptain]

ok fine , i have merge thx for help
