FileNotFoundException - Too many open files

[mhernand40]

Seeing the following crash in production for our Android app:

java.io.FileNotFoundException: /data/user/0/*********/app_amplitude-disk-queue/cab21925f6ed6f9bb0f53ea20cba9c2b-4.tmp (Too many open files)

Though the number of affected users seems to be low; less than 50 users or so.
