ERROR: SSL_write, code: 336195711

Hi,

I/m encountering this error when I enable TLS in linux 14.04
I'm using swift 3.0.1 and kitura 1.1.2
It's working if TLS is disabled.

Fixed in BlueSSLService v0.11.56. Refreshing your dependencies should get the fix.

BlueSSLService is now in v0.11.56 but still the same error

ERROR: handleWriteHelper() IncomingSocketHandler.swift line 194 - Write to socket (file descriptor 7) failed. Error = Error code: 336195711, ERROR: SSL_write, code: 336195711, reason: bad write retry.

I ran the exact same test here before posting the fix and I can't reproduce it. The only difference was I was using my certificates and running on Ubuntu 16.04. Can you provide a bit more information? What request triggered the error? Or did the error appear immediately? If it appeared immediately, it's likely a problem with your certs. Any more information you can provide would be extremely helpful. Thanks in advance.

Been doing more research into this problem. Turns out the fix I put in is good but only for non-blocking sockets. I need to make some more changes.

[billabt]

The complete fix for this is now in. However, it resulted in a version change for BlueSSLService and BlueSocket. Kitura-net depends on these and will need an update to Package.swift before the changes will be picked up by Kitura. I've tested the changes here (again on 16.04) and can not reproduce your problem. I'd still like to get more information from you regarding what triggered the error. Thanks.

Fixed as part of #858 per @billabt.

I'm still having this issue with latest Kitura 1.6.1. However it seems like it only happens when I try to request content over the static file server that is more than 100KB (like bootstrap.min.css). Hope that helps.

@foldericon This looks to be the same issue as #1036
I've submitted a pull request (Kitura/BlueSSLService#21) to BlueSSLService to fix the issue. Please let us know if this resolves the issue. Thanks!

@foldericon This has been fixed in SSLService-0.12.29. Please verify it works ok now by deleting your Packages directory and fetching/building again. Thanks!
