good day. We have a server where we write the ndvr archive using wowza streaming engine. CentOS release 6.7, Intel (R) Xeon (R) CPU E5530 @ 2.40GHz, 5gb ram, 1tb hdd, 1gb / s network. The last week, the wowza(java) process was crashed every 18-20 hours and the entire archive that was recorded for 30 hours is deleted.Process java is still here, but CPU has 0% load. helps restart wowza. we use WowzaStreamingEngine-4.2.0 and we write 10 streams. error that always appears in the logs "HTTPStreamerAdapterCupertinoStreamer.service: Request timeout: 8000"; "HTTPStreamerAdapterCupertinoStreamer.onPlaylist: DVR Store not found [Archive/undefined/playlist.m3u8?DVR&wowzadvrplayliststart=20190720084700&wowzadvrplaylistduration=7200000]: undefined:null"
