This describes issues caused by the RAM Disk running out of space and what to do about it.
Looking at the protocolstats files stored at these locations:
There are non-zero values for the nospace column. This means that the MTP is dropping packets because there is no space to write them out. The nqnapacapd
should also have an error message showing this.
The file system that these packets are written out is the RAMdisk of /nqtmp/tim (in MTP 2,2 and later) and /nqtmp/headers. The area allocated for these tmpfs file systems have been exceeded. By default, it is either 2 GB or 4 GB depending on MTP configuration.
There are two fixes for this:
Support Engineers may also suggest additional steps based on pcap analysis and after consulting the internal MTP Support documentation.
