Hi

 

In middle of run the process resulted in deadlock 

Following is the stack got after doing pstack to the process which uses
unixODBC 

 

Does SQLRowCount result in lock? 

And what SQLTablesW  means?

 

#0  0x005ec7a2 in _dl_sysinfo_int80 () from /lib/ld-linux.so.2

#1  0x0085513e in __lll_mutex_lock_wait () from /lib/tls/libpthread.so.0

#2  0x00851d9b in _L_mutex_lock_35 () from /lib/tls/libpthread.so.0

#3  0xb69d0fb8 in ?? ()

#4  0x009edbfc in ?? () from /usr/lib/libodbc.so.1

#5  0x08121c00 in vtable for stbThreadFIFO ()

#6  0x90dbb328 in ?? ()

#7  0xb69d0fb8 in ?? ()

#8  0x009d254a in SQLTablesW () from /usr/lib/libodbc.so.1

#9  0x009d254a in SQLTablesW () from /usr/lib/libodbc.so.1

#10 0x009b72b9 in SQLRowCount () from /usr/lib/libodbc.so.1

 

Thanks,

Bhavik
