/dev/urandom can indeed run out of entropy if it is called repeatedly.

Sorry for bumping the old thread.
So does that mean say i repeatedly generate seeds say 100 seeds one after the other before finally deciding the choose the seed for my wallet. Does that make the seed less secure?

no it doesn't. /dev/urandom can generate unlimited cryptographically secure random numbers. it doesn't run out.

It doesn't run out that's too.
But there's something definitely there is?
I tried it. I created seeds in electrum wizard. After 30,40 seeds the wallet closed. (may be randomness was weakening? ) . I again open and tried. Same happened again.
Also the post i quoted. Electrum developer also confirmed /dev/urandom can run out of entropy if it is called repeatedly.
Found similar concern here as well - https://bitcoin.stackexchange.com/questions/62871/does-my-electrum-wallet-become-less-secure-if-i-keep-generating-seeds-until-i-se
