I think this was previously mentioned by Paul Melson... try to use IP
addresses in your IPsec interesting traffic ACL... I agree with him, that
having specific ports in ACL1 is the problem, as far as I know

So ACL1 is now:
access-list ACL1 extended permit tcp host 192.168.11.11 host 10.1.100.13 eq
4000
access-list ACL1 extended permit tcp host 192.168.11.11 host 10.1.110.250 eq
4000
access-list ACL1 extended permit tcp host 192.168.11.11 eq ftp host
10.1.100.105 eq ftp
access-list ACL1 extended permit tcp host 192.168.11.11 host 10.1.100.105 eq
ftp-data
access-list ACL1 extended permit tcp host 192.168.11.12 host 10.1.100.13 eq
4000
access-list ACL1 extended permit tcp host 192.168.11.12 host 10.1.110.250 eq
4000
access-list ACL1 extended permit tcp host 192.168.11.12 host 10.1.100.105 eq
ftp
access-list ACL1 extended permit tcp host 192.168.11.12 host 10.1.100.105 eq
ftp-data

ACL1 should be:
access-list ACL1 extended permit ip host 192.168.11.11 host 10.1.100.13
access-list ACL1 extended permit ip host 192.168.11.11 host 10.1.110.250
access-list ACL1 extended permit ip host 192.168.11.11 host 10.1.100.105
access-list ACL1 extended permit ip host 192.168.11.11 host 10.1.100.105
access-list ACL1 extended permit ip host 192.168.11.12 host 10.1.100.13
access-list ACL1 extended permit ip host 192.168.11.12 host 10.1.110.250
access-list ACL1 extended permit ip host 192.168.11.12 host 10.1.100.105
access-list ACL1 extended permit ip host 192.168.11.12 host 10.1.100.105

At least try this config, and see if it works... worst case roll it back to
what you had before.

Do a 'debug cry isa 5' and try to ping a remote host from e.g. 10.1.100.13
and see if the tunnel tries to build
