** [tickets:#926] AMF: assert in standby amfd, ckpt of si_dep_state**

**Status:** accepted
**Milestone:** 4.3.3
**Created:** Fri May 23, 2014 10:54 AM UTC by Hans Feldt
**Last Updated:** Fri May 23, 2014 10:55 AM UTC
**Owner:** Hans Feldt

Installing an application that includes an SI dependency ends up like this on 
the standby amfd:

~~~~
#0  0x00007f71264bcb35 in raise () from /lib64/libc.so.6
No symbol table info available.
#1  0x00007f71264be111 in abort () from /lib64/libc.so.6
No symbol table info available.
#2  0x00007f7127d51e07 in __osafassert_fail (__file=<optimized out>, 
__line=<optimized out>, __func=<optimized out>, __assertion=<optimized out>)
    at sysf_def.c:401
No locals.
#3  0x00000000004103e7 in dec_si_dep_state (cb=0x69c980, dec=<optimized out>) 
at avd_ckpt_dec.c:2042
        status = 1
        si_ptr_dec = 0x7fffb986d1d0
        dec_si = {tree_node = {bit = 0, left = 0x0, right = 0x0, key_info = 
0x0}, name = {length = 50,
~~~~
my analysis is that this is a race condition when the standby amfd as applier 
has not yet got the SI from IMM and therefore when the si_dep_state is 
checkpointed the object does not exist. Just yet another variant of the same 
problem we have had before (due to race with being applier).
