azure - Unhealthy Worker role is not restarting and waiting for the status -


i have worker-role, 4 instances, external tcp/ip endpoint. after several days running without problems, instances began die, 1 after one.

in 24 hours of them in status: "waiting status (role has reported unhealthy.)".

all of them sending "working" verbose log (from run method), not accepting incoming connections. how happen ? unhandled exception thread ?

why of them not restarted after several hours , of them "waiting status" ?

if they're endlessly repeating startup-shutdown-restart cycle, 1 possibility have startup task works first time it's run fails on subsequent runs (ie, not idempotent).

otherwise, in startup process causing problem, it's hard without more information. try rdp machines , @ windows event logs, , else can think of, clues.

you might try reimaging 1 or 2 instances , see if fixes problem. @ least tell if problem in base code, or if vm got unrecoverable state.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
