Describe the bug srt crash under very heavily congested networks To Reproduce some conditions to reappear this core dump

  1. a heavily congested network
  2. send data under file mode
  3. do not modify SRTO_LINGER opptions
  4. use async mode

Expected behavior srt crash will be happened after one or two hours Screenshots stack trace: image image

Desktop (please provide the following information):

  • OS: Android
  • SRT Version:1.4.3rc

Additional context I reviewd srt code, I found that , when I use async mode and do not modify SRTO_LINGER, srt will let gc thread to release resources; so the GC thread and the sender thread may have some thread synchronization problems; so I set SRTO_LINGER to off and 0, this crash never happened again; but I dont know to use which lock to solve this problem appropriately
