F4v file corrupted after live recording AMS 5.0.5r5012 FP15

Two separate issues below:

1. f4v file can it be salvaged?(we can provide logs and file if need be)
   • running flvcheck we get:
     • moof/traf/trun/ 84
     • moof/traf/tfhd/ 28
     • moof/traf/trun/ 596
     • moof/traf/trun/ 84
     • moof/traf/tfhd/ 28
     • moof/traf/trun/ 28
     • Memory Overhead: 64698 bytes
     • 14-09-18 10:50:19 BPH0_new.f4v passed
   • the f4v file is 725,876 KB  its supposed to be 56:55  in a player duration reads 10:01 and will only play up to that point.
   • Is there anything else that can be done to salvage the file?
   • 
     
2. Recorded files not matter which type/codec. results in 0kb file size:
   (this issue has been happening in all known versions of AMS since 4.5 on Windows)

• inconsistent issue, 1 in 15, with files(*any type, f4v,flv audio or video)
• during a live recording,  0kb file size is produced. 
• The streams transmits fine to all connected users.
• having the user stop and start/append doesn't resolve the issue
• using different record applications (*all using netstream.publish()) doesn't resolve the issue

any Ideas?
