This error is caused by running out of direct memory when trying to allocate memory for uploading a file through a proxy. The Java Virtual Machine (JVM) uses direct memory for ByteBuffer objects used by Netty, a popular networking library used for building high-performance network applications. Direct memory is memory outside of the Java heap and is allocated using the operating system's memory management system. The error message indicates that the JVM has used up almost all of its available direct memory, leaving only 4 MB available, which is not enough to allocate the memory needed for the file upload. The maximum amount of direct memory available to the JVM is 2 GB (2147483648 bytes). To fix this error, you can try increasing the maximum amount of direct memory available to the JVM by setting the -XX:MaxDirectMemorySize JVM option. For example, you can set this option to 4 GB by adding the following to your JVM arguments: ``` shell -XX:MaxDirectMemorySize=4g ``` This will increase the maximum amount of direct memory available to the JVM to 4 GB, which should provide enough memory for the file upload. Alternatively, you can try reducing the amount of direct memory used by your application by optimizing your code or reducing the size of the files being uploaded. You can also try using a different networking library that uses less direct memory or that allows you to configure the amount of direct memory used. -- This is an automated message from the Apache Git Service.
