No, the report that you posted shows that apache has been running for a long
time:
enough to generate 3,603,022 errors. If apache has any timeouts associated
with starting up, then there's a good chance that finding and suppressing
all those errors has consumed the timeout. (What was the wall-clock duration
of the run with 3603022 errors?)

Search the web for "valgrind libcrypto.so apache" and find:
14. Why does Valgrind complain about the use of uninitialized data?
Follow the directions given there, and similarly for other crypto libraries.
After you have "tamed" the crypto code, then look at the errors that are
counted by "suppressed: 2131 from 15". If there are any real surprises,
then deal with those, too.
Finally, post again if/when there is something interesting.
