For those following this conversation at home...the OP and I have been communicating off-thread, diagnosing the issue. The root cause is some logging-related code in mod_sftp, which appears to be fixed in the latest code in the master branch on GitHub. The context in which the segfault occurs is not related to AWS or the 'aws s3 sync' command, or really even related to sshfs (which is the client talking to mod_sftp). Other SFTP clients might encounter/trigger the segfault, depending on the logging configuration used. Two commits which relate to the fixing of this issue are: https://github.com/proftpd/proftpd/commit/b5c407771e8aaa41811199e595116bfe0f36afb9 https://github.com/proftpd/proftpd/commit/6699802a930f51080acd37a5735a97b7050bcaff Cheers, TJ ------------------------------------------------------------------------------ Developer Access Program for Intel Xeon Phi Processors Access to Intel Xeon Phi processor-based developer platforms.
