Any idea what this means:

type=SYSCALL msg=audit(1236769790.766:247): arch=40000003 syscall=11
success=yes exit=0 a0=9d1e668 a1=9d23e50 a2
type=EXECVE msg=audit(1236769790.766:247): argc=4 a0="/bin/sh"
a1="/sbin/service" a2="sshd" a3="restart" 
type=EXECVE msg=audit(1236769790.766:247): argc=3 a0="/bin/sh"
a1="/sbin/service" a2="sshd" 
type=CWD msg=audit(1236769790.766:247):  cwd="/root"
type=PATH msg=audit(1236769790.766:247): item=0 name="/sbin/service"
inode=189083 dev=fc:01 mode=0100755 ouid=0 
type=PATH msg=audit(1236769790.766:247): item=1 name=(null) inode=251907
dev=fc:01 mode=0100755 ouid=0 ogid=0 rd
type=PATH msg=audit(1236769790.766:247): item=2 name=(null) inode=315525
dev=fc:01 mode=0100755 ouid=0 ogid=0 rd

Note that there are 2 EXECVE records there. This was generated by RHEL
5.3 i386.

Thanks,

Matt

Something went wrong that shouldn't have?  File a BZ and CC me so I'll
remember to take a look.  A reproducer would be GREAT!  Multi-part
execve records can be normal (if the execve logging is too long to for a
single audit message), but this is about x1.75 of a single record.
Doesn't seem right.
