  • If one uploads a large npm package using npm publish, this could cause Nexus to run out of memory as it parses the POSTed JSON payload.   Reproduce with the following: Artificially reduce the Nexus 3 max heap size to 256mb Artificially create a large npm package to publish: # Create a 25mb file ([http://unix.stackexchange.com/q/33629]) head -c 25M </dev/urandom > big.file # Include big file in package.json $ cat package.json | grep files "files" : [ "big.file" ]   Attempt to npm publish while the Nexus 3.3 and below has the logger  {noformat} org.sonatype.nexus.internal.web.ErrorPageServlet{noformat} at DEBUG.   You will see:   {noformat} 2017-03-28 21:26:11,020+0000 DEBUG [qtp1560565746-42] *SYSTEM
