avc: denied { ptrace } messages

[Radha Venkatesh (radvenka)]

During the startup of one of our process, I notice a lot of avc denial
messages for ptrace, as shown below. I have tried the suggestions by
audit2allow, used the various macros for ptrace (also pasted below), but
nothing seems to work. Could you help?

The audit2allow tools suggests the below
 
allow servm_t audisp_t:process ptrace;
allow servm_t auditd_t:process ptrace;
allow servm_t crond_t:process ptrace;
 allow servm_t setrans_t:process ptrace;
allow servm_t sshd_t:process ptrace;
allow servm_t sysadm_t:process ptrace;
allow servm_t udev_t:process ptrace;
 
However, when these rules were added, there was no change in the avc
messages. I also tried the macro
 
domain_ptrace_all_domains(servm_t)
 
and 
 
allow servm_t self:capability { sys_ptrace };
 
But none of this makes a difference to the avc messages generated.
 
Thanks,
Radha.
