INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10

Problem reproduces running IDS 12.10.UC4W1 on linux x86_64. 
 
The front end cdr client will hang with following stack: 
 
$ rasu pstack 4524 
#0  in __kernel_vsyscall () 
#1  in __nanosleep_nocancel () from /lib/libc.so.6 
#2  in sleep () from /lib/libc.so.6 
#3  in checkReplset () 
#4  in cdr_check () 
#5  in check_replset () 
#6  in main () 
 
and the backend session seems to be waiting for the client as 
its thread is in cond wait netnorm.
